Patent CA-2173413-A1 (CA)
Title: Methods of cancellation and compositions therefor
Inventor: GRAHAM IANTHE ELIZABETH MURRAY
IPC: G07D7/12
Filed: 1996-04-03
Abstract: The invention relates to the cancellation of printed values by use of colour former/colour developer systems. Thus the invention provides ink compositions for conferring a value on an article, the compositions comprising a taggant having a characteristic UV absorption or emission spectrum to indicate said value and a first component of a two component colour former/colour developer system wherein the composition contains sufficient of said first component so that when the second component of said colour former/colour developer system is applied to the first component, the colour developed masks and effectively cancels the value indicated by the taggant. The invention also provides articles coated with the ink compositions and methods of cancelling printed values by use of the compositions.

Title: Customer information control system and method with temporary storage queuing functions in a loosely coupled parallel processing environment
Inventor: PHILLIPS MARK
IPC: G06F9/46
Filed: 1996-05-21
Abstract: The present invention is a distributed computer system having a plurality of end user terminals and a plurality of loosely coupled server computers that share no resources with each other.  A multiplicity of user application processes are distributed over the server computers. A temporary storage file is stored on a first one of the server computers, for temporarily storing queues of data records.  Each user  application  process responds to execution of a WriteQ TS instruction specifying data to be stored in a specified temporary storage queue by generating and storing at least one TS data record in the temporary storage file representing  the specified data. Each TS data record has a primary key indicating the record's position in the specified temporary storage queue.  Each TS data record is stored in the same temporary storage file on the first server computer regardless of which server computer executes the WriteQ TS instruction.  Each user application process also responds to execution of a ReadQ TS instruction specifying a temporary storage queue from which data is to be retrieved, by reading at least one TS data record from the temporary storage file.

Title: Dual Bias Weld for Continuous Coiled Tubing
Inventor: STAGG ROBERT E
IPC: B21C37/08
Filed: 1994-12-02
Abstract: A dual weld for joining strips to be formed into coiled tubing. Tubing is formed from a first strip (15a) and a second strip (15b), the first and second strips of the same width. A planar end surface (Pa) is formed on an end of the strip. Similarly, a planar end surface (Pb) is formed on an end of the second strip. A composite strip is formed by welding the planar end surface of the first strip to the planar end surface of the second strip to form a dual bias weld. Excess-weldment is then removed from top, bottom and edge surfaces of the composite strip such that the width of th weld is identical to the width of the first and second strips. Coiled metal tubing is then formed from the composite strip.

Title: System and method for selecting training text
Inventor: BUCHSBAUM ADAM LOUIS
IPC: G10L13/02
Filed: 1996-05-31
Abstract: A system and method are described for determining a near-optimum subset of data, based on a selected model, from a large corpus of data. Sets of feature vectors corresponding to natural or other preselected divisions of the data corpus are mapped into matrices representative of such divisions. The invention operates to find a submatrix of full rank formed as a union of one or more of those division-based matrices.  A greedy algorithm utilizing Gram-Schmidt orthonormalization operates on the division matrices to find a near optimum submatrix and in a time bound representing a substantial improvement over prior-art methods.  An important application of the invention is the selection of a small number of sentences from a corpus of a very large number of such sentences from which the parameters of a duration model for speech synthesis can be estimated.
Patent CA-2180758-A1 (CA)
Title: Wellbore sand control method
Inventor: JONASSON RALPH G
IPC: E21B33/138
Filed: 1996-07-08
Abstract: A slug of solution, comprising a linear polymer such as polysulfone, polyethylene terephthalate or polyimide dissolved in a "good" solvent, such as morpholine, m-cresol or dimethylsulfoxide, respectively is emplaced in the near- wellbore region of an unconsolidated sand reservoir. A second slug comprising a poor solvent for the polymer, such as water or water + 2-methanol is pumped into the region to contact the first slug. The linear polymer is precipitated and forms a three-dimensional network of interconnected strands extending through the fluid flow channels between the sand grains. The network functions to consolidate the sand without significantly damaging permeability.

Title: Method of assembling log walls for log house and clamping bolt to couple the wall
Inventor: FUTAGI KOHZOH
IPC: E04B2/70
Filed: 1996-11-19
Abstract: A first story log house material is adhered to a base with a coach bolt and succeeding log materials after a second story are piled up in turn with clamping bolts.   A coach bolt or a clamping bolt has a height corresponding with one long thickness and is equipped with a nut portion and a wahser. This method of assembling log walls for the log house eliminates the accumulated shrinkage for the log wall during the drying period. Thus,by the present invention, it is now not necessary to prepare some large size of a side adjusting device and also to reserve some large settling space, both of which are unavoidable in prior art.

Inventor: MILLER LAWRENCE E
IPC: B61G9/08
Filed: 1997-04-30
Abstract: A railcar cushioning device includes an elastomeric spring and a hydraulic shock absorber member. The fluid accumulator is located outside of and above the fluid chambers. The accumulator is in communication with the fluid chamber in a non-stroked position, causing entrapped air to be displaced by the fluid, into the accumulator. Free of air, the shock absorber immediately responds to impact forces. The elastomeric spring reduces peak impact forces and returns the piston of the shock absorber to its non-stroked position. The elastomeric spring also absorbs draft forces.
